HTC-1600 Coil Processing Equipment for Lithium Battery Cover & Aluminum Parts

Product Overview

Automatic uncoiler with loading car

The purpose of the feeding platform trolley is to facilitate the loading and unloading of materials, making it safer and faster when handling heavy rolls. The large automatic unwinding machine is designed to secure the materials and work in conjunction with the straightening machine to slowly guide the material head into the straightening machine, then automatically unwind. It is equipped with a powered pressing arm to prevent material from spilling during unwinding, while also pulling the material head to make it easier for the material to enter the leveling machine. The special hydraulic sliding block expansion method can bear heavier loads than the ordinary connecting pin structure, capable of supporting heavy rolls of up to 10 tons, ensuring more stable unwinding operations.

Leveling machine

The material leveling machine corrects and levels the material through upper and lower leveling rollers, in conjunction with an uncoiler and high-speed NC feeder. The leveling rollers are arranged with six on top and five on the bottom, made of bearing steel SUJ2, with the roller surfaces processed by wire electroplating and grinding.

NC Feeder

The NC feeder can achieve high-speed and efficient feeding. This machine uses a numerical control operating system, and its user-friendly design and operating concept allow users to quickly become proficient in operating it. The feeding rollers have a hollow structure, resulting in low rotational inertia, high feeding accuracy, and a long service life. The rollers are made of bearing steel and are subjected to high-frequency treatment, tempering, grinding, and hard chrome plating. After feeding with this machine, the materials are smooth and even without any indentations, ensuring that the surface of the materials is not damaged. The main machine has a strong steel structure, high output power, and stable feeding.

Loop Bridge

During the feeding process, there is no need for manual lifting of materials, and the steel coils can be smoothly delivered to the feeding machine. The steel coils can be buffered by the material arc to ensure that the material belt length can be conveyed into the feeding machine. Hydraulic power is used for lifting and lowering, with a buffering bridge spanning the ends of the leveling machine and the feeding machine. It is raised during feeding and lowered during connected operation. Two sets of photoelectric switches are installed at the material arc, controlling the speed conversion of the leveling machine to ensure that the hanging plates have sufficient length for storage. The material support rollers are covered with rubber on the bearing surface to prevent the material from scratching the surface during passage.

Application Display: Precision Stamping for Lithium Battery Components

The HTC-1600 Heavy-Duty 2-in-1 Uncoiler Leveler Feeder Line is widely used in the new energy lithium battery industry, especially for the automated stamping of precision components such as square aluminum casings, battery covers, and aluminum terminals (poles).

By integrating uncoiling, leveling, and feeding functions, the system ensures high flatness and positioning accuracy before stamping, resulting in consistent product quality and dimensional precision.

Typical stamping results include:

Aluminum casings with high strength and excellent sealing performance;

Battery covers formed with multiple punching and bending operations;

Aluminum terminals processed with precise blanking and punching for optimal electrical and assembly performance.

Why Choose HTC-1600 Coil Processing line？

The HTC-1600Coil Processing line is purpose-built to meet the high precision and surface protection requirements of the new energy industry, especially for lithium battery components like aluminum housings, cover plates, and aluminum terminals.

Here’s why it’s the ideal choice for your coil handling and stamping line:
